Configuring
Create a basic configuration file:
cat > /etc/xinetd.conf << "EOF" # Begin /etc/xinetd # Configuration file for xinetd # defaults { instances = 60 log_type = SYSLOG daemon log_on_success = HOST PID USERID log_on_failure = HOST USERID cps = 25 30 } # All service files are stored in the /etc/xinetd.d directory # includedir /etc/xinetd.d # End /etc/xinetd EOF
Create the /etc/xinetd.d directory:
install -v -d -m755 /etc/xinetd.d
Create files within the /etc/xinetd.d directory as placeholders, in case you should need to set up these services at a later date:
